Low Engine Idle Solution:

Issue: Low engine idle (most observed in hot weather, it comes and goes) car vibrates rough idle at 600rpm. CVT rough response and car jerks very little during RUN and STOP.
(NOTE: The best rpm are 800rpm or 900rpm)
(This is the issue in my 2016 Honda Civic Touring TURBO 1.5Liter)

I fixed it by following the solution i have found. It works for me, hope for you gys too.


1. Press the button FRONT defrost inside the weather control switch. The Low engine idle e.g. 600 rpm will become immediately 800-850rpm. Engine power will be constant and CVT transmission will response immediately. works 100% till you have FRONT weather Defrost button ON.

2. Press ON the AUTO = Auto control weather and SYNC = Synchronize control weather buttons. The Low engine idle e.g. 600 rpm will become immediately 800rpm. Engine power will be good and CVT transmission will response good. Works 95% till both buttons are ON.

- It looks there is a connection between some of the power functions with engine & CVT power. If you go to dealer they will not fix it. they will play with you and try to get money out of you, that problems of spark plug, filter, injector, software, carburetor, bad gas, timing belt etc. etc.

- Request: Some one please write to Honda engineers or the CEO of Honda company to fix properly.
